Hello im have recently got a new graphing calculator calculator for school (9th grade). In maths im currently doing trigonometry with sin cos and tan. I am very basic in my programming skills so im asking for help with a program.

i want a program that can find angles and sides of a right angle triangle. i have a Casio fx CG 20. I want the program to first ask me where i want to find an angle or a side length and then i enter the information needed to find the angle or side length. Thank you.

Graphing Calculator Very Happy
Well for solving a triangle, it's pretty much using the law of sines and the law of cosines to solve them. If you know those, you could implement pretty much any case of solving a triangle.

something like this is what im looking for

This is an excellent opportunity to practice some programming, so if you haven't read any tutorials already, try looking one up on Google, they will teach you the basics you need to now to accomplish this.

The functions that you can use are:

Please please please use the code tags when posting code!

Edit: Thank you for the fix!
Thank you Smile that was greatly appreciated Very Happy
when i put the program in to my prizm and run it it gives me a syntax error. i think that might be that I've installed it incorrectly or that the first command "'ProgramMode:run" is wrong because when i go into then code and skip through it, it goes by each individual letter instead of skipping until the and as it would to for any other command such as "then" or "else" where would i find the "'ProgramMode" command in my calculator?
first press new and make a name for the program "trisolve" and then hit run in the bottom left corner of the screen on your calc. Next copy the code and then place it in this program and delete the first line with the program run in it and this should work
It's not because of the first line (it is ignored because it is a comment), it's because every single line has a space at the end. See my post: http://www.cemetech.net/forum/viewtopic.php?p=215183#215183
